I just switched to funtoo, and I'm curious about the repository differences. What I've heard is that the funtoo repository is similar to the gentoo testing repository, but it uses more stable internals. How bleeding edge is the funtoo repository compared to gentoo testing? What counts as an internal package, is it any command-line utility, or system-vital packages? And finally, how up to date are the internal packages when compared to, say, gentoo stable?
